A man of mass 60 kg records his wt. on a weighing machine placed inside a lift. The ratio of wts. Of man recorded when lift is ascending up with a uniform speed of 2 m/s to when it is descending down with a uniform speed of 4 m/s will be

A man of mass 60 kg records his weight on a weighing machine placed inside a lift . The ratio of the weights of the man recorded when the lift is ascending up with a uniform speed of 2 m/s to when it is descending down with a uniform speed of 4 m/s will be

A person of mass 60 kg stands on a weighing scale in a lift (elevator). What would the scale read if the elevator moves (i) up with a uniform speed of 5 m//s (ii) down with a uniform acceleration of 4 m//s^2 (iii) up with a uniform acceleration of 4 m//s^2 ? [Given : g = 10 m//s^2 ]

A man is standing on a weighing machine placed in a lift. When stationary his weight is recorded as 40 kg . If the lift is accelerated upwards with an acceleration of 2m//s^(2) , then the weight recorded in the machine will be (g=10m//s^(2))

A man is standing on a weighing machine placed in a lift. When stationary his weight is recorded as 40 kg . If the lift is accelerated upwards with an acceleration of 2m//s^(2) , then the weight recorded in the machine will be (g=10m//s^(2))

A body of mass 50kg is put on a spring weighing machine in a lift What is the reading of the machine when (i) Lift ascends with a unifrom velocity of 10m//s (ii)descends with an acceleration of 5m//s^(2) ? Take of = 10m//s^(2) .

A body of mass 50 kg is hung by a spring balance in a lift. Calculate the reading of the balance when : The lift is ascending with an acceleration of 2m//s^(2) .

A body of mass 50 kg is hung by a spring balance in a lift. Calculate the reading of the balance when : The lift is descending with a constant velocity of 2 m/s.

A man of 60kg mass is in a lift. Find the apparent weight of the man when the lift is moving up with uniform speed( g=10ms^(-2))

A boy of mass 50kg is standing on a weihing machine placed on the floor of a lift. The machine reads his weight in newtons. The reading of the machine if the lift is moving upwards with uniform speed of 10ms^(-1) .

A man of mass 70 kg stands on a weighing scale in a lift which is moving (a) upwards with a uniform speed of 10 m s^1 (b) downwards with a uniform acceleration of 5 m s^2, upwards with a uniform acceleration of 5 m s-^1z. What would be the readings on the scale in each case? What would be the reading if the lift mechanism failed and it hurtled down freely under gravity?
